what are steel pipe caps?
Oct. 10, 2020
The cap is a part of the container. According to the different geometric shapes, it can be divided into: spherical, elliptical, dish-shaped, spherical cap-shaped cone shell and flat cap, among which spherical, elliptical, dish-shaped, spherical cap The head is also collectively called the convex head.
In terms of welding, it is divided into: butt welding head and socket welding head.
Used in various container equipment, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment, etc.
The materials are carbon steel (A3, 20#, Q235, Q345B, 16MN, etc.), stainless steel (304, 321, 304L, 316, 316L, etc.), alloy steel (15Mo3 15CrMoV 35CrMoV 45CrMo), aluminum, titanium, copper, nickel and nickel Alloy etc.
The steel pipe cap is the end cap on the pressure vessel and is a main pressure-bearing component of the pressure vessel. The role played is the sealing effect.
1. The upper and lower bottoms of the tank-shaped pressure vessel are made
2. The end of the pipe is the end, and it is not ready to extend forward, then use a head to seal the pipe in the form of welding.
There are blind plates and caps that are similar to the functions of the head, but those two products are detachable. After the head is welded, it cannot be disassembled. The matching pipe fittings include pressure vessels, pipes, flanges, elbows, tees, crosses and other products. The quality of the head is directly related to the long-term safe and reliable operation of the pressure vessel.
